In the 20th year of the Republic of China, Shen Rangchen, a once famous architect in Peiping, lost his wife's life, the flexibility of his right hand, and the reason to live due to a scaffolding collapse accident. He escaped from the world in Meiwu, a small town in the south of the Yangtze River, opened a grocery store "Chen Ji", and lived like an isolated island.
Su Mian is a new female gentleman in town, and she rents the yard next door to him. She didn't ask him why he always kept the back door of his shop closed, or why he burned a stack of paper by the river on the fifteenth day of every month. She just put a pot of hot water at his door every morning and took away the empty pot in the evening, day after day, without interruption.
Three years and more than a thousand days. Separated by half a door and a wall, the two used a pot, a lamp, and a plate of walnuts to live their lives like a love letter that will never be signed.
It wasn't until the autumn of the 23rd year of the Republic of China that a letter from Peiping revealed a secret that had been buried for ten years - the accident that year was not an accident. The person who was really responsible for the accident was Su Mian's late father.
She came to Meiwu initially to atone for her sins. She stayed because she was moved.
And after he knew the truth, he ended everything with one sentence. That sentence is not "I hate you", it is "You go away".
